  • any way to get sharepoint groups with a given site url

    - by standley-nguyen
    Hi all. I'm getting a stuck. Suppose that I create 5 sites. For each one, I create a few sharepoint groups. So, I create a dropdownlist control to bind 5 sites and when I click on any site there, I will get sharepoint groups created on it. But I always see the dropdownlist used to bind these groups still never change. I mean it only binds a few default groups in sahrepoint everytime. The new created groups is not. And I have confusion like this web.AssociatedGroups web.Groups web.SiteGroups which one we will use this case ? Please guide me Here my snippet code private void BindSPGroupsToDropDownList(DropDownList ddl, string siteUrl) { ddl.Items.Clear(); try { SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(siteUrl)) { using (SPWeb web = site.OpenWeb()) { //web.SiteGroups foreach (SPGroup spGroup in web.Groups) { ddl.Items.Add(new ListItem(spGroup.Name.Trim(), spGroup.ID.ToString())); } } } }); } } thanks in advance

  • WxWidgets custom events

    - by Klaus
    Hello, I'm trying to use a custom event in my WxWidgets C++ application, like described here. In the constructor of my wxApp: Connect(wxID_ANY, wxCommandEventHandler(APP::OnMyEvent)); Then the function that should catch the event: void APP::OnMyEvent(wxCommandEvent& event) { exit(0); //testing } Finally, to test it: wxCommandEvent MyEvent(wxEVT_COMMAND_BUTTON_CLICKED); wxPostEvent(this, MyEvent); I launch the thing...but it seems that the event is not posted or not caught. Does someone understand this behaviour ?

  • How do I make this ASP.NET MVC controller more testable?

    - by Ragesh
    I have a controller that overrides OnActionExecuting and does something like this: protected override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); string tenantDomain = filterContext.RouteData.Values["tenantDomain"] as string; if (!string.IsNullOrWhiteSpace(tenantDomain)) { using (var tx = BeginTransaction()) { this.Tenant = repo.FindOne(t => t.Domain == tenantDomain); } } } Tenant is a protected property with a private setter. The class itself is an abstract base controller that my real controllers derive from. I have code in other controllers that looks a lot like this: if (Tenant == null) { // Do something } else { // Do something else } How do I test this code? What I need to do is to somehow set the Tenant property, but I can't because: It's a protected property, and It has a private setter Changing the visibility of Tenant doesn't "feel" right. What are my alternatives to unit test my derived controllers?

  • Thoughts on try-catch blocks

    - by John Boker
    What are your thoughts on code that looks like this: public void doSomething() { try { // actual code goes here } catch (Exception ex) { throw; } } The problem I see is the actual error is not handled, just throwing the exception in a different place. I find it more difficult to debug because i don't get a line number where the actual problem is. So my question is why would this be good? ---- EDIT ---- From the answers it looks like most people are saying it's pointless to do this with no custom or specific exceptions being caught. That's what i wanted comments on, when no specific exception is being caught. I can see the point of actually doing something with a caught exception, just not the way this code is.

  • Modifying reference member from const member function in C++

    - by Philipp
    I am working on const-correctness of my code and just wondered why this code compiles: class X { int x; int& y; public: X(int& _y):y(_y) { } void f(int& newY) const { //x = 3; would not work, that's fine y = newY; //does compile. Why? } }; int main(int argc, char **argv) { int i1=0, i2=0; X myX(i1); myX.f(i2); ... } As far as I understand, f() is changing the object myX, although it says to be const. How can I ensure my compiler complains when I do assign to y? (Visual C++ 2008) Thank a lot!

  • Why doesn't this work?

    - by user146780
    I'v tried to solve a memory leak in the GLU callback by creating a global variable but now it dos not draw anything: GLdouble *gluptr = NULL; void CALLBACK combineCallback(GLdouble coords[3], GLdouble *vertex_data[4], GLfloat weight[4], GLdouble **dataOut) { GLdouble *vertex; if(gluptr == NULL) { gluptr = (GLdouble *) malloc(6 * sizeof(GLdouble)); } vertex = (GLdouble*)gluptr; vertex[0] = coords[0]; vertex[1] = coords[1]; vertex[2] = coords[2]; for (int i = 3; i < 6; i++) { vertex[i] = weight[0] * vertex_data[0][i] + weight[1] * vertex_data[0][i] + weight[2] * vertex_data[0][i] + weight[3] * vertex_data[0][i]; } *dataOut = vertex; } basically instead of doing malloc each time in the loop (thus the memory leak) im using a global pointer, but this doesn't work (drawing to the screen). Why would using malloc to a pointer created in the function work any different than a global variable? Thanks

  • Write problem - lossing the original data

  • Gapless (looping) audio playback with DirectX in C#

    - by horsedrowner
    I'm currently using the following code (C#): private static void PlayLoop(string filename) { Audio player = new Audio(filename); player.Play(); while (player.Playing) { if (player.CurrentPosition >= player.Duration) { player.SeekCurrentPosition(0, SeekPositionFlags.AbsolutePositioning); } System.Threading.Thread.Sleep(100); } } This code works, and the file I'm playing is looping. But, obviously, there is a small gap between each playback. I tried reducing the Thread.Sleep it to 10 or 5, but the gap remains. I also tried removing it completely, but then the CPU usage raises to 100% and there's still a small gap. Is there any (simple) way to make playback in DirectX gapless? It's not a big deal since it's only a personal project, but if I'm doing something foolish or otherwise completely wrong, I'd love to know. Thanks in advance.

  • Initializing a char array through passed pointer segfaults

  • wcf possible to override the dipose of proxy

    - by pdiddy
    I'd like to override the Dispose method of generated proxy (ClientBase) because of the fact that disposing of a proxy calls Close and can throw an exception when the channel is faulted. The only way I came up was to create a partial class to my generatedproxy, make it inherit from IDisposable. : public partial class MyServiceProxy : IDisposable { #region IDisposable Members public void Dispose() { if (State != System.ServiceModel.CommunicationState.Faulted) Close(); else Abort(); } #endregion } I did some test and my Dipose method is indeed called. Do you see any issue with this strategy? Also, I don't like the fact that I'll have to create this partial class for every generated proxy. It be nice if I was able to make my proxy inherit from a base class...

  • ViewPager resize height to Content

    - by user1324936
    ViewPager does not wrap its height to its content. For my layout I need to set the hight then dynamically because it is nested in other layouts. Therefore I created a ScrollView as content of the ViewPager and check its height in onCreate method of the Fragment, but the ScrollView has always the same size. How can I resize the ViewPager to fit to its content? final ScrollView sv = (ScrollView) v.findViewById(R.id.sv); ViewTreeObserver vto = scrollViewMenuFragen.getViewTreeObserver(); vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() { @Override public void onGlobalLayout() { int height = sv.getMeasuredHeight(); //always same height independent of content height //need to resize ViewPager ViewGroup.LayoutParams params = (ViewGroup.LayoutParams) mPager.getLayoutParams(); params.height = height; mPager.setLayoutParams(params); } });

  • Redirecting the response from a filter throws an IllegalStateException

    - by Ritesh M Nayak
    I am writing a filter that will handle all authentication related tasks. My filter is a standard servlet filter as shown below @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { UserSession attribute = (UserSession)request.getSession().getAttribute("user_session_key"); if(attribute!=null && attribute.isValid()) { //proceed as usual, chain.doFilter(req, res); return; } else { //means the user is not authenticated, so we must redirect him/her to the login page ((HttpServletResponse)res).sendRedirect("loginpage"); return; } } But when I do this, I get an IllegalStateException thrown by Tomcat's ResponseFacade. How do I acheive this in a filter. I read in other SO threads that in TOmcat this is a problem as the response object is already commited. How do I get past this ?

I found similar code to this on msdn and I can't get it to work. protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { e.Row.Cells[2].Text = e.Row.Cells[2].Text + "random text"; } I also tried similar code in the Page_PreRender event with no luck. I have also tried calling DataBind() before this one line of code with no help. I always just get "random text" in the cell without the data from the DB. Thanks

  • How to make an scrollable UITextField Inside UItableViewCell?

    - by user333624
    Hello everyone. I created a bunch of editable UITableViewCell by embedding an UITextField inside, but I have seen some apps that allows you to scroll the UItableview by scrolling inside an inactive editable cell. How can I do that? And how can I also dismiss the keyboard when tapping somewhere else? I know about the method: - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; if (touch.tapCount == 1) { [self resignFirstResponder]; } else { }} I put it inside my custom table view controller but the method doesn't seem to be called upon a tap, and I don't know if even if it gets called will dismiss the keyboard. Any help will be appreciated.

Cannot find out whats wrong. Kindly help
